Abstract

PURPOSE: To obtain the titled resin giving a powder paint excellent in stability, smoothness and luster, by the esterification of terephathalic acid, etc. with a diol and the addn. of trimellitic anhydride while OH gp. still remains unreacted, followed by additional esterification and polycondensation.
CONSTITUTION: A dicarboxylic acid (A) consisting of 50W100mol% (hereinafter referred to as %) terephthalic acid, 0W50% isophthalic acid and 0W20% other linear aliph. dicarboxylic acids is esterified with a diol (B) consisting of 0W100% neopentyl glycol, 100W0% ethylene glycol and 0W20% other aliph. linear diols in a mol ratio of (B)/(A) of 0.90W1.20, and the resulting product is further esterified with addition of 0.03W0.10mol, based on the total acid components, of trimellitic anhydride at an arbitrary step where OH value of the residual OH gp. is 50W400 (KOHmg/g), and polycondensed to lower the OH value of the residual OH gp. below 10(KOHmg/g), whereby the titled resin contg. carboxyl gp. in an amt, calculated on acid value, corresponding to 20W100(KOHmg/g).
